They are EN 54-24 certified, so they can be used for voice alarm installations. The speakers are equipped respectively

with a 3" and 4" full range transducers. With 20W and 40W power, both models offer optimal performances for

any kind of application. They integrate high impedance outputs for 100V and 70V installations.

The built-in transformer gives the choice of three or four power levels depending on the model.

Made of ABS resin the cabinet is scratch and shock resistant.
